Don't do it, I live a kilometre away from a haunted house, I've entered at least six times, it's a house which an old man died, the place hasn't been stepped in by buyers or even on market to sell, it's as if it doesn't exist any more.
You enter and the door will close behind you, you enter his office and draws will slide out, the wooden things on the windows will flap open and shut, my friend was locked in a cupboard while he was looking through the mans porn catalogues, if some things are touched you feel it suddenly get colder.
Haunted houses are not to be messed with.
Cameras that detect heat signatures, electronic disturbance equipment detectors like like emfs, people say salt actually works but I'm not sure.
